Description of auto continous powder coating line
Your products need to be coated: Electrowelded galvanized mesh coils ; Application of finished products: fence system for highway, railway & industrial factory; Max. size of workpiece: Length: 30000mm × Width: 2500mm; Output: ≥3-5m/min; Heating source: electricity; Power consumption: installed capacity 170kw, average power 150kw; Water consumption: 2.5-3.0m3/h (circulated water); Powder application method: auto application by fluidized bed; Required size of coating factory: 30×10×5m(L×W×H)
Process flow: ①Manual feeding mesh coil on our de-coiler → ②Pre-heating furnace → ③Auto powder coating in fluidized bed → ④Curing furnace → ⑤Water cooling on coated mesh → ⑥Manual discharging of finished coil → ⑦Manual shaping correction → ⑧Quality control → ⑨Final package
Brief description: The metal fence is first preheated to a certain temperature and then passed through a fluidized bed of plastic powder where the powder particles melt, adhere and flow out to form a smooth continuous PVC coating. It is then post-heated to complete the curing of the outer surfaces. Both pre-heating furnace and curing furnace are natural gas heated.
